Vulnerability discussion

If a user can write to the audit logs, then audit trails can be modified or destroyed and system intrusion may not be detected.

Check content

Check the audit configuration to determine the location of the system audit log files. # more /etc/security/audit_control Check the system audit log files for extended ACLs. # ls -la [audit log dir] If the permissions include a "+", the file has an extended ACL and this is a finding.

Fix text

Remove the extended ACL from the file. # chmod A- [audit file]

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
